Problems solved by technology

Although some studies have tried to achieve the purpose of integrating light energy conversion devices onto other circuits by fabricating light energy conversion devices similar to integrated solar cells (ISCs) using P-N junction photodiode technology derived from CMOS processes, This kind of photodiode shows low photoelectric conversion efficiency, which is not enough to provide enough power to the circuit in the chip

Abstract

A unit pixel element that acts as an image sensor or a solar cell according to the present invention comprises a photo detector that drives a photocurrent flow, induced by light incident onto the gate, along the channel between the source and the drain; a first switch that is wired and switched on or switched off between the source terminal of the photo detector and the first solar cell bus; and a second switch that is wired and switched on or switched off between the gate terminal of the photo detector and the second solar cell bus, and features a function of light energy harvesting and high-efficiency photoelectric conversion that generates and supplies effective electric power.

Description

technical field [0001] The present invention relates to an image sensor that can be used as a solar cell and an electronic device using the image sensor with a solar cell function, and particularly relates to an Used as a technology for solar cell operation. Background technique [0002] Light energy harvesting wirelessly charges existing batteries by converting light energy into electrical energy. Various electronic devices in these fields provide semi-permanent power supply. [0003] Therefore, light energy harvesting technology requires miniaturization and integration. Although some studies have tried to achieve the purpose of integrating light energy conversion devices onto other circuits by fabricating light energy conversion devices similar to integrated solar cells (ISCs) using P-N junction photodiode technology derived from CMOS processes, This kind of photodiode shows low photoelectric conversion efficiency, which is not enough to supply enough power to the circu...
